FIELD

The present application relates to grills and outdoor cooking systems.More specifically, the present application relates to a grill assemblywith a foldable cart.

BACKGROUND

Grilling is a cooking style that is especially popular in the UnitedStates. Grills are frequently not particularly portable or easy to setup. In many cases, grills are difficult to assemble due to numeroussteps requiring the user to construct a frame with numerous components.

Attempts have been made to design grills that are easy to assemble afterunloading from shipping containers. However, in many past systems, grillsystems include a large number of pieces, require numerous steps toassemble, and some assembly steps require tools.

Some past systems mount a firebox on a foldable stand. However, thefoldable stands can require complex set-up steps and, even in the foldedconfiguration, some of the foldable stands take-up significant space.

Permanent outdoor grill installations are increasingly popular, andallow consumers to choose many finishes and options to create anattractive and functional outdoor kitchen environment. Theseinstallations are very expensive, and lack the flexibility of a moveablegrill system.
